Place of death is a Long Island town or village, not the five boroughs and not the Nassau County Clerk. NYC Health will not issue it. Albany will issue statewide copies. Start with the local registrar if you can.
Who may request
Follow the local registrar and New York State Vital Records rules. Confirm who may request on the town clerk page and on health.ny.gov.
What to bring
Photo ID as the local registrar lists. Confirm before you mail. The county clerk's $5 authentication fee is not the copy fee.
Where to write or visit
Nassau County Clerk does not keep birth or death certificates. Use the clerk or registrar of the town, city, or incorporated village of death (Hempstead, North Hempstead, Oyster Bay, and the villages). Statewide mail: New York State Department of Health, Vital Records, Albany. This is not NYC Health.
Notes from the desk
There is no single Nassau County death-copy price on the county clerk page this check. Town registrars set local fees (example: Town of Hempstead lists $10 per copy on its own site; confirm on the town you actually need). State mail fees are on health.ny.gov. This desk takes no cut. Do not invent a county-wide dollar amount.
